See xref:further-concepts/unit.adoc#letting-through-events[].

Matched events:: If checked, even MIDI events matched by at least one mapping are let through.
If unchecked (default), such events are filtered out.

Unmatched events:: If checked (default), MIDI events that are not matched by any mappings are let through.
If unchecked, such events are filtered out.

Check out xref:user-interface/main-panel/menu-bar.adoc#match-even-inactive-mappings[] to fine-tune matching behavior.
